IMPROVEMENT lN WASH-BOARDS.

' Specification forming part of Letters Patent N0. 219,026, dated August 26, 1879; application filed March 29,1879.

To all whom it may concern:

Be it known that I, FRANKLIN Mormon SMITH, of Thivener P. 0., in the county of Gab lia and State of Ohio, have invented a new and useful Improvement in Wash-Boards, of which the following is a specification. My invention relates to improvements in the manufacture of wash-boards, with a view to reducing the cost of manufacture, and at the same time producing a superior article.

The invention consists in a novel construction of the frame of the wash-board, and of bars used in connection therewith, to forma rubbin g-surface for the clothes, whereby provision is made for placing the bars in position, and for removing them and chan gin gtheir positions when they become worn.

The accompanying drawings represent a wash-hoard constructed according to my invention, Figure 1 being a side view, and Fig. 2 a longitudinal section in the line a- .70.

Similar letters of reference indicate corresponding parts.

The frame of the wash-board is composed of two side rails, A A, connected by a lower bar, 13, an upper bar, 0, and a head-rail, D. The side rails,A, are provided with mortises a, for the reception of the ends of the bars E, which form the rubbing-surface. These mortises are of quadrangular form, and arranged diagonally with relation to the length of the rails A.'

The bars E are of corresponding form, and when in place in the frame the two opposite angles of each'bar form part of the rubbingsurface, while the intermediate angles are in line with the corresponding angles of the other bars, and thus the whole series of bars produce the same effect as a corrugated surface.

The bars may be either close together or far enough apart to allow the water to run through, as'may be preferred. 7

The bars E are made of zinc, and in order to render them strong and solid andprevent them from being bent or battered, they are provided with a filling consisting of wooden bars fitting snugly in them, as represented in secto the positions formerly occupied by the angles first used, and thus form a sharp new rubbing-surface. Moreover, if the bars in one portion of the board should become more worn than other portions, their positions maybe reversed, so as to place the bars which are least worn in the positions of those which are most worn. I

Having thus described my invention, I claim as new and desire to secure by Letters Patent An improved wash-hoard having its rubbing-surfaces formed by quadrangular removable bars E, held in correspondingly-shaped mortises a, cut diagonally in the side rails, A, by the detachable strips G, substantially as and for the purpose set forth.
